The journey

What the journey actually looks like

Direct or connecting, how far the route really runs, and what happens when a connection is missed.

Direct or connecting
20% of the services we sell on this corridor run through without a change. The remaining 80% involve one connection.
How far it really runs
The route covers 2,399 km against 2,329 km in a straight line, a detour of 3 percent. Track and road geometry account for the difference.
Where the change is
Connections are made at Minneapolis, Salt Lake City, Spokane, Denver. The gap between arriving and leaving is 59 minutes, of which about 5 is walking.
If the connection is missed
The tightest connection we sell here has a 16 percent chance of not being made on the timetable alone. Part of this journey is a self transfer between separate tickets, so leave more time than the minimum and expect to check in again.
First and last departure
The first service of the day leaves Chicago at 06:19 and the last at 07:30, across 5 departures. The return direction keeps its own timetable, so the times back are not these times reversed.

Where these numbers come from

Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.

Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
